The patch that was posted on freebsd-mobile
(against PAO3-beta-19990329) lets my laptop see the modem and
use it. However, after a few minutes of modem activity, the PPP connection
hangs, requiring me to either quit PPP or close PPP to reestablish it.
After quitting/closing PPP, I do not need to reboot to see the modem
again (I can do a term from the PPP session with success).
Here's a sample of some of the ping times (this is with light Netscape+
NNTP activity):

When icmp_seq gets to about 194, it wedges.
However, when I configure pccard.conf to use pio instead of IRQ 3, the
wedging doesn't occur. But, it is significantly slower.
BTW, Here's the output of dmesg:

Judging from the fact that pio does work, it seems to me like it is a
problem with the interrupt handling code.
What could the problem be?
